- 5 tablespoons unsalted butter: Essential for browning, it adds a rich, nutty flavor that elevates the entire treat.
- 1/4 teaspoon vanilla extract: Adds warmth and rounds out the sweetness with a hint of aromatic complexity.
- 10 cups mini marshmallows (divided): Provide the gooey texture; the division ensures layers have varying chew and softness.
- 6 cups Rice Krispies cereal: Offers that beloved crisp crunch to contrast the softness of the marshmallows.

How to Make Brown Butter Dulce de Leche Rice Krispie Treats Recipe
Step 1: Prepare the Pan
Start by lightly spraying a 9×9-inch baking pan with non-stick spray. This simple step ensures your treats will release easily when it’s time to cut and serve, saving you from any sticky frustrations later on.
Step 2: Brown the Butter
Over medium heat, melt the butter in a large pot while stirring constantly. Keep a careful eye as it transforms into a golden brown color and releases a warm, nutty aroma. This is the flavor jackpot that sets the tone for the entire recipe, adding layers of depth to your treats.
Step 3: Melt Marshmallows
Add 8 cups of the mini marshmallows to your browned butter and stir gently until the marshmallows are completely melted and silky smooth. Remove from heat, then stir in the vanilla extract and fine-grain sea salt to bring additional flavor nuance and a subtle balance to the sweetness.
Step 4: Combine with Cereal
In a large bowl, pour the melted marshmallow mixture over the Rice Krispies cereal. Stir everything until the cereal is evenly coated, making sure each bite will have that perfect chewy crunch combination. Then fold in the remaining 2 cups of mini marshmallows — this adds delightful pockets of soft marshmallow in every bite.
Step 5: Assemble Layers
Press half of the coated Rice Krispies mixture firmly into the prepared pan, creating a solid base. Spread the dulce de leche evenly over this bottom layer, ensuring every bite will have a creamy caramel surprise. Finish by topping with the remaining Rice Krispies mixture, pressing gently to make an even surface without squishing the marshmallows too much.
Step 6: Set and Serve
Let the treats cool at room temperature for about 30 minutes, allowing them to set perfectly and making them easier to slice. Then cut into generous squares and prepare to amaze your friends and family with this luscious twist on an all-time classic.
How to Serve Brown Butter Dulce de Leche Rice Krispie Treats Recipe

Garnishes
To really make your Brown Butter Dulce de Leche Rice Krispie Treats Recipe shine, consider sprinkling a pinch of flaky sea salt on top right after pressing the final layer. Toasted nuts such as chopped pecans or almonds also complement the buttery, caramel notes beautifully and add an enticing crunch.
Side Dishes
These treats are already decadent, but if you want to create a dessert spread, pair them with simple vanilla ice cream or a dollop of whipped cream. The cold creaminess balances the chewy, warm flavors perfectly and rounds out your sweet table.
Creative Ways to Present
If you want to impress, serve these treats on a rustic wooden board, sliced into fun shapes using cookie cutters, or even wrapped individually in parchment paper tied with twine for a charming homemade gift. Their rich caramel and buttery aroma make them irresistible no matter how you present them.
Make Ahead and Storage
Storing Leftovers
Keep your Brown Butter Dulce de Leche Rice Krispie Treats in an airtight container at room temperature. This will preserve their perfect chewiness and flavor for up to 3 days, making them a great make-ahead snack or dessert.
Freezing
If you want to save them longer, wrap individual pieces tightly in plastic wrap and store them in a freezer-safe bag or container. They freeze very well for up to 2 months. When you’re ready to enjoy, just thaw at room temperature for a few hours.
Reheating
To reawaken their gooey goodness, warm your treats briefly in the microwave for about 10-15 seconds per piece. This brings back the softness and lets the dulce de leche shine through beautifully, almost like fresh out of the pan!
FAQs
Can I use regular-sized marshmallows instead of mini ones?
Absolutely! Regular marshmallows will work just fine, but you might want to chop them into smaller pieces to help them melt evenly and coat the cereal thoroughly.
Is dulce de leche easy to find, or can I make it at home?
Dulce de leche can often be found in the international aisle of most grocery stores or Latin markets. If you’re feeling adventurous, you can make it at home by slowly simmering sweetened condensed milk until it caramelizes, but store-bought options save time.
Can I substitute Rice Krispies with another cereal?
Yes, you can experiment! Crisp cereals like cornflakes or puffed rice work well, but keep in mind it will alter the texture. This recipe shines with the classic crunch of Rice Krispies.
Does browning the butter affect the final taste much?
Definitely! Brown butter gives these Rice Krispie treats a deeper, nuttier flavor that makes them stand out. Skipping this step would mean missing out on a key layer of richness.
Can I make these treats gluten-free?
Yes! Just be sure to use a gluten-free Rice Krispies or substitute with a gluten-free puffed rice cereal. The rest of the ingredients are naturally gluten-free.
Final Thoughts
There is something truly special about the comforting nostalgia of Rice Krispie treats combined with the sophisticated flavors of brown butter and dulce de leche. This Brown Butter Dulce de Leche Rice Krispie Treats Recipe offers a perfect balance of gooey, crunchy, salty, and sweet that will delight your taste buds and warm your heart.
